TECHNICAL FIELD

The present invention relates to a weight training machine, and more particularly, to a weight training machine in which weight plates capable of increasing or decreasing weight and an operation bar configured to perform movement by pulling a cable are connected to each other via a cable, thus enabling a user to perform exercises, including a deadlift, bent-over row, and the like during weight training.

BACKGROUND ART

Generally, exercise machines are divided into exercise machines for upper body training and exercise machines for lower body training, and these exercise machines include weights, weight of which is appropriately adjustable according to a user, to allow a user to perform upper body or lower body muscular exercise.

For example, a lower body exercise machine is a fitness machine that strengthens calf muscles and thigh muscles of the lower body of a user, and an upper body exercise machine is a fitness machine that strengths back and shoulder muscles or arm muscles of a user.

As such, to do a deadlift, a bent-over row, and the like during weight training, a weight bar may be used by inserting barbells and weight discs thereinto according to a user.

FIG. 1 is a view illustrating a conventional exercise method.

Referring to FIG. 1, to increase or decrease the weight of a weight bar, when barbells or weight discs are removed therefrom or inserted thereinto, it is inconvenient for a user to sustain the weight of the barbells or the weight discs.

In addition, when a user exercises, cases of basic posture imbalance frequently occur, and thus a user may be injured.

In addition, when performing deadlift, bent-over row, and the like using a weight training machine, it is difficult to express tensile strength as weight values, and, even though tensile strength is expressed as weight values, weight cannot be freely increased or decreased due to limitations thereof.
